CONCRETE BLOCK.

Application filed March 16, 1922.

The invention has to do withconcrete or` cement blocks for fabricationinto walls of different thicknesses and of one or many courses with theblocks interiitting and held together by intermediate layers of mortaror other cementitious material, either joining the blocks together atabutting portions and arranged about a common axis as in the formationof drains or the like, or where the blocks are arranged in courses withthe sides and ends of the blocks in contact and also the faces oftheblocks in contact.

In the preferred form of the invention, the cement blocks are each ofsegmental form with a tongue along one long edge and a groove along theother long edge so that the blocks may be assembled in interlockingengagement and the ends of the blocks, these blocks being longer in onedirection than in the other, are likewise capable of interlocking.Extended lengthwise through the block is a centrally disposed duct sothat when the blocks are placed end to end, the ducts will coalesce intoa long or unbroken passageway with the walls of the passagewaysufficiently thick to impartk the requisite strength to the structuremade up of the blocks. i

In the segmental form of the invention, one face, preferably the outerface of the block is formed with numerous parallel re` inforcing ribshaving the function of preventing the blocks from slipping in the mouldswhen green concrete is in course of transportation between the mouldingmachine and the drying or curing shed.l

The invention will be best understood from a consideration of thefollowing detailed description taken in connection with the accompanyingdrawings forming part of this specification with the understanding thatthe invention is not confined to any strict conformity with the showingof the Serial No. 544,119.

drawing but may be changed andmodiiied so long as such changes andmodifications mark no material departure from the Lsalient features ofthe invention as expressed in the appended claims.

In the drawings Figure l is a cross section through a lpipelikestructure made up of a plurality of segmental blocks joined end to endand side to side in the form of a pipe, these blocks being arranged inalternation about the longitudinal center line of the pipe. Fig, 2 is aside elevation of one of the blocks, with surface reinforcing ribs.

Fig. 8 is a perspective view from Ione end of the block illustrated inFig. 2. i

Fig. 9 is a similar perspective view 'taken from the other end thereofand appearing more particularly in Fig. 3. Since the lconcrete blocksare all alike it is only necessary to describe one block for thedescription will apply to all the blocks employed, especially as to themanner of constructing these blocks.

In forming the blocks, vthe usual 4procedure of fabricating concreteblocks isV followed and in itself does not form any part 0f theinvention. y

Referring to the drawings, which all relate to the same general form ofblocks, there is shown a block l of generally elongated segmental formandadapted particularly to be assembled into the shape of a pipe or ductwith numerous of the blocks l grouped about a common axis. Each blockcomprises a. body member 2y of somewhat elongated con# tour with meetingsides 3 and i arranged generally on radii meeting at the center of thepipe or drain made up of a suitable number of blocks 1.

Extending centrally and longitudinally through each block 1 is a passage5, preferably though not necessarily of tubular outline.

The passages or holes 5 are long" enoughnzto` extend completely througheach block 1` midway of the sides and topv and bottom .surfaces of theblock and may be used as an air duct or drainageduct. in wet trench orfor other purposes. vOtherwise than that as stated the block is solid.

One end of the block is formed centrally with a transverse groove 9,intersecting the opening 5, and with the upper wall 9 and lower'wallVQfzof the groove 9 provided intermediatetheends thereof with a curvedportion,4 andthe saidy curved portions are indicatedat'., 5f", and formycontinuations oit the wall of the opening Theremaining.

portions of the walls 9', 9 are 'bevelled Thedowerv.,wallf'9f2ofthe'groove'9, at one end :terminates in an upwardly extending`projection 14, *having a curved.- inner side, and the'othier end` of thebottom' wall 9" of the' groove 9f1nerges into an upwardly d isposedproj'ection 13, having its vinner side curved. "The projection `14, isintegralwith the bodyasndthe `projection 13 is not only integral withthebody 2, but also with the tongue-6to be'presently referred to.. 'Theinner sides of the projections 13, 14, are oppositelfydisposedwi'threspect to each other.

'i The projection 14, is overhung by one end of two sections, and withone of the sections the-top^wa'll 9 of the groove 9.

Formed integral with the other end ofthe block 1,".centrally thereof,"isa transversely extendingvbevelled' split tongue, formed of.

j of the block land said'section18is -of greater length than thesection8. The inner side ofeach of the sections 8, 8', is curved as at 8, andthe saidinn'er sides of the sections 8,'y 8f' form eontinuations of thewall of the openingf.y :The'bottom of `each ofthe sections 8, 8. at theouter ends is undercut as at 8.-:The undercuts 8 are oppositely7disposed with respectto each other and cor` isfinserted in a transversegroove the wall of i the inner wall of the'groove?.

thel opening 5, will be extended to the end of f the block. i

One .sideof the block 1, centrally thereof,

`is formed with ailongitudinal groove. 7, having the u aper and lowerwallsy thereof hevelled.4 ne end ofr theY groove 9 merges into thegroove 7,. at one `end thereof, above the projection 14, and. the outerface 14 of the latterjforins one end terminal portion of Thev other sideof the block 1, centrally thereof,-,is `forined Awiththe tongue 6, the

latter is integral with thejbodyvportion 2 of the block and extendslongitudinally thereof. The tongue G, is bevelled and has the portion 8of the split tongueintegral with one end thereof.v L

The groove 7 of one block is adapted to receive the longitudinal. tongue6 of an adjacent block andthe shape of the tongue corresponds in contourto thev shape of the groove. 'f 4Wherever. .the block. lcornes intoContact thereis' .introduced y,a layer v15 of mortary or otherappropriate cementitious materiale/of acting with thev contactingsurfaces ofthe blocks fito yeffectively anchor the blocks togetherlongitiidinally-v and .circumferentially.v The segmental blocks areintended-more particularly forV curved contours, such as are found indrain pipes andthe like, withthe passages ,5 for, use as supplemental,due-ts.
